NASA has provided Armadillo Aerospace and Masten Space Systems a total of $475,000 to help fund test flights of suborbital vehicles. The funding, part of NASA’s Commercial Reusable Suborbital Research program, will help pay for three flights by Armadillo’s Super-Mod vehicle and four flights by Masten’s Xaero. Flights are expected to reach between 3 and 25 miles in altitude.
